Code

Cause

Cause

1 BIOS checksum failure. Possible system board failure. Contact Dell.

2 No memory modules are detected

1. If you have two or more memory modules installed, remove the modules, reinstall one module, and then restart the computer. If the computer starts normally, reinstall an additional module. Continue until you have identified a faulty module or reinstalled all modules without error.

2. If available, install good memory of the same type into your computer. 3. If the problem persists, contact Dell.

3 Possible system board failure Contact Dell.

4 RAM Read/Write failure 1. Ensure that no special memory module/memory connector placement requirements exist. 2. Verify that the memory modules that you are installing are compatible with your computer. 3. If the problem persists, contact Dell.

5 Real-time clock failure. Possible battery failure or system board failure.

Replace the battery. If the problem persists, contact Dell.

6 Video BIOS Test Failure Contact Dell.

7 CPU-cache test failure Contact Dell.

Diagnostic Lights

To help troubleshoot a problem, your computer has four lights labeled 1, 2, 3, and 4 on the bank panel. When the computer starts normally, the lights flash before turning off. If the computer malfunctions, the sequence of the lights help to identify the problem.


NOTE: After the computer completes POST, all four lights turn off before booting to the operating system.

Light Pattern Problem Description Suggested Resolution

The diagnostic lights are not lit after the computer successfully boots to the operating system.

l Plug the computer into a working electrical outlet. l If the problem persists, contact Dell.

A possible processor failure has occurred.

l Reseat the processor (see Processor information for your computer). l If the problem persists, contact Dell.

Memory modules are detected, but a memory failure has occurred.

l If two or more memory modules are installed, remove the modules, then reinstall one module and restart the computer. If the computer starts normally, continue to install additional memory modules (one at a time) until you have identified a faulty module or reinstalled all modules without error.

l If available, install working memory of the same type into your computer. l If the problem persists, contact Dell.

A possible graphics card failure has occurred.

l Reseat any installed graphics cards. l If available, install a working graphics card into your computer. l If the problem persists, contact Dell .

A possible floppy drive or hard drive failure has occurred.

Reseat all power and data cables.

A possible USB failure has occurred. Reinstall all USB devices and check all cable connections.

No memory modules are detected. l If two or more memory modules are installed, remove the modules, then reinstall one module and restart the computer. If the computer starts normally, continue to install additional memory modules (one at a time) until you have identified a faulty module or reinstalled all modules without error.

l If available, install working memory of the same type into your computer. l If the problem persists, contact Dell.

Memory modules are detected, but a memory configuration or compatibility error has occurred.

l Ensure that no special requirements for memory module/connector placement exist. l Ensure that the memory you are using is supported by your computer (see the Specifications

section for your computer). l If the problem persists, contact Dell.

A possible expansion card failure has occurred.

l Determine if a conflict exists by removing an expansion card (not a graphics card) and restarting the computer.

l If the problem persists, reinstall the card you removed, then remove a different card and restart the computer.

l Repeat this process for each expansion card installed. If the computer starts normally, troubleshoot the last card removed from the computer for resource conflicts.

l If the problem persists, contact Dell.

Another failure has occurred. l Ensure that all hard drive and optical drive cables are properly connected to the system board .

l If there is an error message on the screen identifying a problem with a device (such as the floppy drive or hard drive), check the device to make sure it is functioning properly.

l If the operating system is attempting to boot from a device (such as the floppy drive or optical drive), check system setup to ensure the boot sequence is correct for the devices installed on your computer.

l If the problem persists, contact Dell.

After Working Inside Your Computer


CAUTION: Only a certified service technician should perform repairs on your computer. Damage due to servicing that is not authorized by Dell is not covered by your warranty.

CAUTION: To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically touching an unpainted metal surface, such as a connector on the back of the computer.

CAUTION: Handle components and cards with care. Do not touch the components or contacts on a card. Hold a card by its edges or by its metal mounting bracket. Hold a component such as a processor by its edges, not by its pins.

CAUTION: When you disconnect a cable, pull on its connector or on its pull-tab, not on the cable itself. Some cables have connectors with locking tabs; if you are disconnecting this type of cable, press in on the locking tabs before you disconnect the cable. As you pull connectors apart, keep them evenly aligned to avoid bending any connector pins. Also, before you connect a cable, ensure that both connectors are correctly oriented and aligned.

NOTE: The color of your computer and certain components may appear differently than shown in this document.

CAUTION: To disconnect a network cable, first unplug the cable from your computer and then unplug the cable from the network device.

CAUTION: Before touching anything inside your computer, ground yourself by touching an unpainted metal surface, such as the metal at the back of the computer. While you work, periodically touch an unpainted metal surface to dissipate static electricity, which could harm internal components.

CAUTION: To avoid losing data, save and close all open files and exit all open programs before you turn off your computer.
